Hong Kong's graft buster on Tuesday charged a former close aide to Hong Kong Chief Executive Leung Chun-ying with perverting the course of justice.
Lew Mon-hung, 64, former deputy chairman and executive director of Pearl Oriental Oil Ltd., will appear in court on Wednesday.
He faces "one count of doing acts tending and intended to pervert the course of public justice," according to a statement by the Independent Commission Against Corruption.
Lew is alleged to have sought the termination of an ICAC investigation against him by intimidating Leung and ICAC commissioner Peh Yun-lu.
"I believe Hong Kong's law is just," Lew told Cable TV Hong Kong. "The whole truth will be revealed. The public will be the judge on whether the ICAC has been used as a political tool (against me)," he said.
The ICAC, with the backing of a court order, asked two media organizations on Aug. 7 to hand over notes, and uncut voice and video recordings of an interview conducted with Lew in January.
In the interview, Lew revealed an unspoken deal he allegedly made with Leung.
Specifically, Lew said he was promised he would be appointed to the Executive Council, Leung's Cabinet, in return for his help in garnering Beijing's support for Leung ahead of Hong Kong's leadership election.
The deal fell through, with Leung reportedly promising that he would recommend that Lew retain a delegate seat in the Chinese People's Political Consultative Conference, but in the end Leung broke his promise again and Lew lost his delegate post.
Lew was arrested by the ICAC in January for alleged bribery related to his petrol investment business but was later released on bail.
He was then arrested in February for alleged perjury after reportedly sending a blackmail letter to Leung and again released on bail.
Considered a liberal pro-Beijing politician, Lew had openly called for support of Zhao Lianhai, a Chinese advocate for victims of tainted milk.
He also supported Hong Kong activists involved in several Diaoyu Islands campaigns.
The islands controlled by Japan, which refers to them as the Senkakus, are claimed by China.
